Description
Specifications

The function of a diaphragm seal is to prevent the fluid from coming into direct contact with the instrument. This prevents the instrument from being damaged by obstruction or erosion caused by corrosive, dirty, viscous, or crystallizing fluids or gases.

DS300 series adopts an open membrane design, making it more suitable for high-viscosity or crystallizing fluids, preventing clogging and easy to clean.
